To all whom may concern.'

Be it known that I, FRIEDRICH Traumi, a subject of the German Empire, residing at Ladsphe i. Westphalia, Prussia, Germany, have invented new and useful Improvements in 'Iin Seals; and I do hereby declare the following to be a full, clear, and exact description of the same.

The tin-seals used hitherto, whose halves are united by connecting cross-pieces, showed, when they were put on, the drawback that owing to the length of the crosspiece, the point at which it had to be bent could not be exactly determined, so that uniting the two halves by hand was almost impossible. This drawback is removed in the tin-seal forming the subject of this application by directly uniting, with the shortest possible bridge, the free edges of the upstanding borders of the two halves of the seal, the connecting-cross piece being so short that a bending at any point can not take place, so that practically it can only be bent in one precisely determined point. 'Ihe shifting of the two halves of the seal out of their relative positions is thereby prevented, so that one half can be put into the other far more easily. Moreover both halves of the seal are according to the present invention provided in the center with protuberances projecting into the interior, hetween which the cord of the seal is held fast, the protuberance of one half serving to receive the marks to be stamped i'nto the seal, while upon the other the cord is placed, and the same serves also as a counter-die when the seal is stamped, while the cord constitutes an elastic support for the counter-die during the stamping.

The drawing illustrates a form of construction of the tin-seal according to Ythis invention.

Figures 1 and 2 show an inside View of the opened halves of the seal and a vertical section; Figs. 3 and 4 illustrate the tin-seal with the halves united, before the borders are bent, in a side-view and top-view. Figs. 5 and 6 show the seal after the bending of the borders in a sectional and top-view.

Similar letters refer to similar parts throughout the several views.

rIhe present seal consists of the halves l, 2, of which the latter possesses the raised border-rim 5, to which the disk l is almost directly connected, asthe cross-piece serving to fasten this disk is so short that when Specification of Letters Patent.

the seal is put on it cannot be bent in any place, but only one precisely determined bending-point is practically possible.

When putting on the seal the two cords are placed into the half 2 of the seal provided with the raised border 5 in a manner that they pass out through the cuts 4, 4 (Figs. 2 and 3) made at opposit-e sides'of the same, whereupon t-he covering-disk is bent over in the direction of the arrow (Fig. 2), and, by means of a pair of pincers the rim 5 (Figs. 5 and 6) is turned over upon the covering disk.

In consequence of the fact that there is only a very short cross-piece between the two halves 1,2 of the seal,there is not only avoided a shifting of the same out of their relative positions when the half l is bent, but the seal is also of a perfectly circular shape with a smooth border, without any project-ing parts, so that no one can be injured when the object to which the seal is aflixed is transported, and in order that the improper-opening of the seal may be prevented.

As will further be seen from the drawing, the two halves of the seal are provided with inwardly projecting protuberances t, 71, between which the cords 6 remain firmly secured after the raised rim 5 has been bent (Fig. 5).

When marks are stamped into the protuberance 71, which either takes place simultaneously with the bending of the border or as a separate process, the protuberance 7 forms the counter-die and, at the same Y time, with the cord squeezed in between them an elastic support for the stamping-process. What I claim as my invention and desire to secure by United States Letters Patent is: 1. A sheet metal seal comprising a larger member having a wide upstanding border;

a smaller member adapted to be received by said border and against and over which said border may be folded, said smaller member being directly joined to the free edge of the iipstanding border of the larger inember by the shortest possible bridge.

2. A sheet metal seal comprising two circular members one of which is adapted to be folded upon the other at it-s edges, each member being provided with an inwardly off-set middle portion; and a cord passing through the seal and clamped by and forming a cushion between the oE-set portions.

3. A sheet'metal seal comprising two ciroular members directly connected by the middle portion, and cords passed and shortest possible bridge, one of said memsqueezed between said flat portions.v

bers having an upturned border provided In testimony whereof, I have signed my with a diametrioally opposite recess eXtendname to this speeication in the presence of 5 ing to the body part of the member, the two subscribing witnesses.

other of said members being provided with Y 'a narrow lipturned flange around which said FRIEDRICH TREUDE' border is adapted to Ibe folded and held Witnesses: y fast, the body parts of each of said members JEAN GRUND, 1n being provided with an inwardly oil-set flat CARL GRUND.
